HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 498, 812, 859 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 498, 812, 859 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 498, 812, 859 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 498, 812, 859 is 1.
HCF(498, 812, 859) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 498, 812, 859 is 1.
Step 1: Since 812 > 498, we apply the division lemma to 812 and 498, to get
812 = 498 x 1 + 314
Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 314 and 498, to get
498 = 314 x 1 + 184
Step 3: We consider the new divisor 314 and the new remainder 184, and apply the division lemma to get
314 = 184 x 1 + 130
We consider the new divisor 184 and the new remainder 130,and apply the division lemma to get
184 = 130 x 1 + 54
We consider the new divisor 130 and the new remainder 54,and apply the division lemma to get
130 = 54 x 2 + 22
We consider the new divisor 54 and the new remainder 22,and apply the division lemma to get
54 = 22 x 2 + 10
We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get
22 = 10 x 2 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 498 and 812 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(54,22) = HCF(130,54) = HCF(184,130) = HCF(314,184) = HCF(498,314) = HCF(812,498) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 859 > 2, we apply the division lemma to 859 and 2, to get
859 = 2 x 429 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 859 is 1
Notice that 1 = HCF(2,1) = HCF(859,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
